Objective: To evaluate the influence of antireflux surgery on gastric empty
ing.
Design: Nonrandomized controlled trial 3 months before and after surgical i
ntervention.
Setting: Secondary and tertiary referral center.
Patients and Control Subjects: Twenty consecutive patients (7 women, 13 men
), mean age 49.2 years, with symptomatic. objectively confirmed gastroesoph
ageal reflux disease and 10 healthy control subjects (3 women, 7 men), mean
age 37.3 years.
Intervention: Laparoscopic or open Nissen fundoplication (in 1 case Toupet
180 degrees posterior hemifundoplication).
Main Outcome Measures: Gastric emptying scintigraphy. using solid food, in
control subjects and patients 3 months before and 3 months after the operat
ion; time to halving of the maximal activity and the activity remaining at
60, 100, and 120 minutes.
Results: Preoperative symptoms included pyrosis in 19 of 20 patients and re
gurgitation in 18, Three months postoperatively. 19 patients were symptom-f
ree. The mean time to halving. of the maximal activity decreased from 113 t
o 78 minutes (P = .001). Delayed gastric emptying was found postoperatively
in 3 patients, compared with preoperative values, using activity at 60, 10
0, 120 minutes and the mean time to halving of the maximal activity as the
variables, Compared with control subjects, gastric emptying was slower in p
atients preoperatively and faster postoperatively. but the difference was n
or statistically significant.
Conclusion: Gastric emptying is enhanced after antireflux surgery, along wi
th cessation of symptoms and healing of esophagitis.
